Optical Constants of Water in the 200-nm to 200-µm Wavelength Region

Applied Optics, Vol. 12 Issue 3, pp.555-563 (1973)
Hale, George M; Querry, Marvin R

Abstract

Extinction coefficients k(λ) for water at 25°C were determined through a broad spectral region by manually smoothing a point by point graph of k(λ) vs wavelength λ that was plotted for data obtained from a review of the scientific literature on the optical constants of water. Absorption bands representing k(λ) were postulated where data were not available in the vacuum uv and soft x-ray regions. A subtractive Kramers-Kronig analysis of the combined postulated and smoothed portions of the k(λ) spectrum provided the index of refraction n(λ) for the spectral region 200 nm ≤ λ ≤ 200 µm.

IMS2012 International Microwave Symposium - Friday 22nd June

Friday 22nd June

Sponsors: MTT-4

Organizers: Magda El-Shenawee, University of Arkansas, and Aly Fathy, University of Tennessee

Abstract: The rising interest in the terahertz band of frequency and the recent research in this area have motivated the organizers to foster an IMS workshop to address the state-of-the-art of this new technology. The goal of the proposed workshop is to addresses the recent research progress in terahertz systems, passive and active devices, sources, and imaging algorithms.
The workshop is related to Terahertz Technology and Applications (MTT-6) and Biological Effects and Medical Applications (MTT-10). It is also relevant to RF Nanotechnology (MTT-25), Microwave and Millimeter-Wave Integrated Circuits (MTT-6) and Microwave and Millimeter-Wave Solid State Devices (MTT-7).
The lack of inexpensive and efficient THz imaging systems is a main challenge that faces the advancement of THz research in potential applications from medical imaging to radar and communication systems. The workshop will discuss the state-of-the-art research in THz imaging radar systems, quantum cascade lasers, sources and detectors, surface plasmon based devices, low power sources, spectroscopy, biological sensing, chemical imaging, and pharmaceutical and medical applications. Recent applications of THz imaging include non-destructive evaluation, security screening, inspection of IC devices and packaging, detection of bio-threat, and cancer detection and assessment. THz tomography involves 3D reconstruction of unknown targets and their constitutive material properties. The workshop will discuss rigorous inverse scattering algorithms and the current challenges of available THz experimental data for the practical implementation.

Terahertz pulsed imaging in vivo: measurements and processing methods

Edward P. Parrott; Stanley M. Y. Sy; Thierry Blu; Vincent P. Wallace; Emma Pickwell-MacPherson

Journal of Biomedical Optics 16(10), 106010

Abstract

This paper presents a number of data processing algorithms developed to improve the accuracy of results derived from datasets acquired by a recently designed terahertz handheld probe. These techniques include a baseline subtraction algorithm and a number of algorithms to extract the sample impulse response: double Gaussian inverse filtering, frequency-wavelet domain deconvolution, and sparse deconvolution. In vivo measurements of human skin are used as examples, and a comparison is made of the terahertz impulse response from a number of different skin positions. The algorithms presented enables both the spectroscopic and time domain properties of samples measured in reflection geometry to be better determined compared to previous calculation methods.

Terahertz session at Photonics West 2013

Terahertz, RF, Millimeter, and Sub-Millimeter-Wave Technology and Applications VI (OE106)

Conference Chairs: Laurence P. Sadwick, InnoSys, Inc. (USA); Créidhe M. O’Sullivan, National Univ. of Ireland, Maynooth (Ireland)

Program Committee: Antao Chen, Univ. of Washington (USA); Robert H. Giles, Univ. of Massachusetts Lowell (USA); R. Jennifer Hwu, InnoSys, Inc. (USA); Anthony Murphy, National Univ. of Ireland, Maynooth (Ireland); Michael C. Wanke, Sandia National Labs. (USA); Tianxin Yang, Tianjin Univ. (China)

This conference brings together researchers and engineers from academia, industry, and government laboratories to explore and present work in the frequency range covering approximately 20 GHz (15 mm) to 3 THz (100 μm). Terahertz (THz) technology deals with the generation and utilization of electromagnetic energy covering what is also known as the sub-millimeter wave region of the spectrum. In this region, which lies between the millimeter wave and far infrared spectral regions, materials exhibit properties that can be exploited to advantage for use over a broad range of important technologies and applications.

This conference includes low to high power sources, detectors, systems, both photonic and electronic including both optical and electronic modulated sources, detectors and systems. At THz frequencies, the primary difficulty encountered by scientists and engineers working in this field is the lack of convenient and affordable sources and detectors of terahertz radiation, but this difficulty is gradually changing as new sources and improved detectors are being developed and as the technology continues to mature and broaden. The purpose of this conference is to gather scientists and engineers from a diverse set of disciplines, who are interested in either learning more about terahertz and submillimeter and millimeter wave and RF technology, or who are contributing to the field through their own research, development or manufacturing activities. Disciplines utilizing terahertz technology include physical chemistry (certain molecules or molecular segments exhibit strong resonances in the 10 cm -1 to 100 cm -1 spectral region), military and homeland security (terahertz radiation can penetrate clothing and packing materials but is refl ected by metals and other materials), biomedical technology (tissue exhibits reflection and absorption properties that change dramatically with tissue characteristics), medical and dental, secure short-distance wireless communications (atmospheric water content prevents terahertz radiation from traveling very far), astronomy (the cold background of the universe exhibits a peak in this spectral region), space communications (where the terahertz region is wide open for use) and other disciplines where new, yet-to-be-discovered applications will undoubtedly come forth. Since the low energy associated with terahertz radiation is expected to be no more harmful than infrared or microwave radiation, safety issues are not expected to limit the use of terahertz radiation at low power levels. Papers are solicited in the following and related areas:

Terahertz sources

• solid-state sources, electron beam sources, vacuum electronics sources, frequency mixers, frequency multipliers, parametric oscillators, hybrids, graphene, FET and HEMT sources, gas lasers, quantum cascade lasers and related sources, p-germanium sources, photoconductive switches, resonant tunnelling diodes, backward wave oscillators, new novel devices. RF, sub-millimeter-wave and millimeter-wavesources

• power sources of all types in the range of 20 GHz to 300 GHz and 300 GHz and higher (i.e., from K-band to the higher end of the millimetre wave frequencies and all of the sub-millimeter wave frequency region).

A technique to measure optical properties of brownout clouds for modeling terahertz propagation

Steven T. Fiorino, Jason A. Deibel, Phillip M. Grice, Markus H. Novak, Julian Spinoza,Lindsay Owens, and Satya Ganti

Applied Optics, Vol. 51, Issue 16, pp. 3605-3613 (2012)
http://dx.doi.org/10.1364/AO.51.003605

Abstract

Brownout, the loss of visibility caused by dust resultant of helicopter downwash, is a factor in the large majority of military helicopter accidents. As terahertz radiation readily propagates through the associated dust aerosols and is attenuated by atmospheric water vapor within short distances, it can provide low-profile imaging that improves effective pilot visibility. In order to model this application of terahertz imaging, it is necessary to determine the optical properties of obscurants at these frequencies. We present here a method of empirical calculation and experimental measurement of the complex refractive indexof the obscuring aerosols. Results derived from terahertz time-domain spectral measurements are incorporated into the AFIT CDE Laser Environmental Effects Definition and Reference (LEEDR) software.

.............These scattering measurements were performed with a more advanced terahertz system (TeraView) that provided in excess of 3 THz of bandwidth.  .........

1. Invited lecture: "Filamentation science: from THz generation through molecular science to rain making in air"

by Professor See Leang Chin, Department of Physics, Engineering Physics and Optics, Center for Optics, Photonics and Laser (COPL), Université Laval, Quebec, G1K7P4, Canada, email: slchin@phy.ulaval.ca

Professor See Leang Chin is the Head of the Laboratory of High-Intensity Ultrashort Lasers at the Center for Optics, Photonics and Laser (COPL) of Laval University, Professor Chin is Canada Research Chair (senior), Ultrafast Intense Laser Science. Professor Chin published 11 books and book chapters, authored or co-authored over 350 refereed scientific papers. He is a Fellow of the Optical Society of. In 2011, he received the top award of the Canadian Association of Physicists (CAP), the 2011 CAP medal for lifetime achievement in physics.

Summary: Two-color long range generation of THz pulses through filamentation of femtosecond Ti-sapphire laser pulses in air will be presented. The THz pulses follow the state of alignment and revival of air molecules excited inside the filament core. The THz strength is proportional to the fluorescence of nitrogen. Population trapping in the Rydberg states of the ionic nitrogen molecules seems to be the reason. Air molecules and water vapor in the strong field of the filament core undergo also ionization and fragmentation. Collisional chemistry would result in the generation of HNO3 molecules. In an appropriate environment such as a cloud chamber, the hygroscopic HNO3 molecules would undergo binary collision with the water molecules resulting in condensation into water droplet and snow.

2. Invited lecture: "THz wave air photonics: bridging the “gap” and beyond"

by Professor X.-C. Zhang, the Institute of Optics, University of Rochester, Rochester, NY 12627-0186 USA, email: zhangxc@rochester.edu

Dr. Xi-Cheng Zhang –Parker Givens Chair Professor and Director of The Institute of Optics, University of Rochester. Dr. Zhang has received 26 US patents, published 23 books and book chapters, and authored or co-authored over 300 refereed scientific papers. He is a Lifetime Fellow of IEEE, the Optical Society of America, and the American Physics Society.

Summary: Historically, THz technologies were mainly used within the astronomy community for searching far-infrared radiation (cosmic background), and the laser fusion community for the diagnostics of plasmas. Since the first demonstration of THz wave time-domain spectroscopy in the late 80’s, there has been a series of significant advances (particularly in recent years) on the development of intense sources and sensitive detectors.

THz wave air photonics involves the interaction of intense femtosecond laser pulses with air. The very air that we breathe is capable of generating and detecting THz field.

Abstract 

Terahertz pulsed spectroscopy was used to qualitatively detect ciprofloxacin hydrochloride monohydrate (CPFX·HCl·H2O) in tablets, and terahertz pulsed imaging (TPI) was used to scrutinize not only the coating state but also the density distribution of tablets produced by several manufacturers. TPI was also used to evaluate distinguishability among these tablets. The same waveform, which is a unique terahertz absorption spectrum derived from pure CPFX·HCl·H2O, was observed in all of the crushed tablets and in pure CPFX·HCl·H2O. TPI can provide information about the physical states of coated tablets. Information about the uniformity of parameters such as a coating thickness and density can be obtained. In this study, the authors investigated the coating thickness distributions of film-coated CPFX·HCl·H2O from four different manufacturers. Unique terahertz images of the density distributions in these commercial tablets were obtained. Moreover, B-scan (depth) images show the status of the coating layer in each tablet and the density map inside the tablets. These features would reflect differences resulting from different tablet-manufacturing processes.

Abstract

As an emerging technology, THz spectroscopy has gained increasing attention in the pharmaceutical area during the last decade. This attention is due to the fact that (1) it provides a promising alternative approach for in-depth understanding of both intermolecular interaction among pharmaceutical molecules and pharmaceutical product quality attributes; (2) it provides a promising alternative approach for enhanced process understanding of certain pharmaceutical manufacturing processes; and (3) the FDA pharmaceutical quality initiatives, most noticeably, the Process Analytical Technology (PAT) initiative. In this work, the current status and progress made so far on using THz spectroscopy for pharmaceutical development and pharmaceutical PAT applications are reviewed. In the spirit of demonstrating the utility of first principles modeling approach for addressing model validation challenge and reducing unnecessary model validation “burden” for facilitating THz pharmaceutical PAT applications, two scientific case studies based on published THz spectroscopy measurement results are created and discussed. Furthermore, other technical challenges and opportunities associated with adapting THz spectroscopy as a pharmaceutical PAT tool are highlighted.
